When your furnace is running properly, it should deliver warmth without creating too much noise. While it’s common to notice your furnace making noise as it begins running, other disruptions are showing your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to assist with the best furnace repair in Albuquerque, New Mexico.

1. Furnace Makes a Banging Sound

You might have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These range from gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s essential to set annual furnace maintenance with I-Deal HVAC. One of the things our professionals complete during this work is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can leak carbon monoxide, which is regularly vented away from your home. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, I-Deal HVAC advises turning it off and contacting us at 505-445-1250. Significant natural gas in your furnace or a broken heat exchanger are dangerous issues that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air across your home. If the ductwork wasn’t designed right or is getting old, it can make a lot of noise when your furnace is on. This could be the issue if your furnace makes a banging noise when it shuts off. Call I-Deal HVAC at 505-445-1250 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or chilly air throughout your residence, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be the result of something little, like an unsecure screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and calling our heating specialists at 505-445-1250 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We are aware that maintenance often slips your mind, but our techs can get your furnace heating quietly again fast.

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still hearing sound, I-Deal HVAC can assist you. It’s important to get loose ductwork taken care of quickly, because it can result in comfort troubles in your home and increase your heating costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Switch off your furnace off instantly and reach our professionals at 505-445-1250 for assistance.
